New in Seattle - Tennis Clubs?

I have just moved to Seattle last week and am looking for a racket club to join.  I am 31/M approx 4.0+ and am looking for a way to meet people through tennis.  Is there a best racket club offering competitive clinics, etc.?  I work in Bellevue...and plan on living in Seattle (temp housing in Redmond now).  Any advice would be greatly appreciated.
